“…28 The absorption band in the range of 540–570 cm −1 for La 0.8 FO@PgNS suggested the formation of M–O bonds, where M = La and Fe, and the La–O and Fe–O stretching vibrations corresponded to octahedral LaO 6 and FeO 6 groups present in perovskites. 41–44…”

“…For example, lanthanum-and iron-modified CNT have been disclosed for environmental use (CN2021113842883A 96 ), while a lanthanumgadolinium-iron oxide-perovskite reinforced with CNT showed improved photocatalysis of the degradation of phenol red over the CNT-free perovskite. 97 A CNT membrane was used to activate MnO2 for oxidative degradation of water pollutants. 98 Journal articles describing the use of CNT in environmental remediation are significantly more numerous than patent publications (Figure 6B); the disparity may be due to the lack of economic incentive in environmental remediation which makes incremental improvements or improvements with more expensive materials difficult to implement.…”

Developing new materials for biomedical applications represents a dynamic and fast-growing interdisciplinary field of research. In this study, six emerging areas were identified in nanoscale materials in the context of biomedical applications by leveraging big data from the CAS Content Collection using quantitative analysis based on natural language processing (NLP). These emerging areas in biomaterials include self-healing, bioelectronic, programmable, lipid-based, protein-based, and antibacterial materials. In this perspective, we will examine the use of nanoscale materials in these areas. These uses range from enhancing the physical and electronic properties of materials used to interface with human tissue, to executing complex functions such as programmable drug delivery.

Perovskites are bringing revolutionization in a various fields due to their exceptional properties and crystalline structure. Most specifically, halide perovskites (HPs), lead-free halide perovskites (LFHPs), and halide perovskite quantum dots (HPs QDs) are becoming hotspots due to their unique optoelectronic properties, low cost, and simple processing. HPs QDs, in particular, have excellent photovoltaic and optoelectronic applications because of their tunable emission, high photoluminescence quantum yield (PLQY), effective charge separation, and low cost. However, practical applications of the HPs QDs family have some limitations such as degradation, instability, and deep trap states within the bandgap, structural inflexibility, scalability, inconsistent reproducibility, and environmental concerns, which can be covered by encapsulating HPs QDs into porous materials like metal−organic frameworks (MOFs) or covalent−organic frameworks (COFs) that offer protection, prevention of aggregation, tunable optical properties, flexibility in structure, enhanced biocompatibility, improved stability under harsh conditions, consistency in production quality, and efficient charge separation. These advantages of MOFs-COFs help HPs QDs harness their full potential for various applications. This review mainly consists of three parts. The first portion discusses the perovskites, halide perovskites, lead-free perovskites, and halide perovskite quantum dots. In the second portion, we explore MOFs and COFs. In the third portion, particular emphasis is given to a thorough evaluation of the development of HPs QDs@MOFs-COFs based materials for comprehensive investigations for next-generation materials intended for diverse technological applications, such as CO 2 conversion, pollutant degradation, hydrogen generation, batteries, gas sensing, and solar cells. Finally, this review will open a new gateway for the synthesis of perovskite-based quantum dots.
